scientific name : turnix varia scintillans common name : painted button - quail ( houtman abrolhos ) other name : abolhos painted button - quail the painted button - quail ( houtman abrolhos ) is a conventionally accepted subspecies of the painted button - quail ( condon 1975 ; marchant & higgins 1993 ; storr & johnstone 1984 ) .
there has been only one significant study on the painted button - quail ( houtman abrolhos ) ( blyth et al . 2006 ) .
given that the painted button - quail ( houtman abrolhos ) is confined to five small islands in the houtman abrolhos ( storr et al . 1986 ) , its distribution is considered to be naturally fragmented .
there are no captive populations of the painted button - quail ( houtman abrolhos ) . no population re - introductions have been attempted or proposed .
the painted button - quail ( houtman abrolhos ) is not known to undergo extreme natural fluctuations in population size , extent of occurrence or area of occupancy .
abrolhos painted button - quail ( turnix varius scintillans ) interim recovery plan . wildlife management program no . 63 ( dbca , 2018 ) [ state recovery plan ] .
the painted buttonquail is about 19–20 cm long . it is found in grassy forests and woodlands . it feeds on insects and seeds , and males incubate the eggs for a fortnight and then care for the young .
the generation length is estimated , with low reliability , to be three years ( garnett & crowley 2000 ) . no cross - breeding has been recorded between the houtman abrolhos subspecies and any other subspecies of the painted button - quail , or between the painted button - quail ( houtman abrolhos ) and any other species of bird . it is unlikely that any cross - breeding occurs in the wild because the painted button - quail ( houtman abrolhos ) is the only subspecies of the painted quail - quail , and the only species of the genus turnix , that occurs in the houtman abrolhos ( del hoyo et al . 1996 ; marchant & higgins 1993 ; sibley & monroe 1990 ) .

the painted button - quail ( houtman abrolhos ) is resident on islands in the houtman abrolhos ( storr 1965a ; storr et al . 1986 ) . a sand - bridge allows movement between east and west wallabi islands during low tide , but otherwise individuals are confined to their respective islands with little or no movement between them . no information is available on the home ranges or territories of the painted button - quail ( houtman abrolhos ) .

the painted button - quail is confined to five small locations : north island , east wallabi island , west wallabi island , seagull island and pigeon island in the houtman abrolhos ( storr et al . 1986 ) .
each of the four subpopulations is considered to be important for the long - term survival and recovery of the painted button - quail ( houtman abrolhos ) ( j . blyth 2007 , pers . comm . ) .

no recovery , conservation or threat abatement plans have been prepared for the painted button - quail ( houtman abrolhos ) . however , a brief recovery outline for the subspecies is featured in the action plan for australian birds 2000 ( garnett & crowley 2000 ) .
the population of the painted button - quail ( houtman abrolhos ) is estimated , with low reliability , to comprise of 2000 adult birds ( garnett & crowley 2000 ) . the size of the population had previously been estimated in the low thousands ( garnett 1993 ) .
the diet of the painted button - quail ( houtman abrolhos ) is essentially unknown . it takes scraps from around fishing camps ( storr 1965a ) and , based on observations of the subspecies t . v . varia on mainland australia , probably feeds on a combination of seeds , fruits and insects ( cleland et al . 1918 ; johnstone & storr 1998 ; mckeown 1944 ; rose 1973 ) . the painted button - quail ( houtman abrolhos ) forages on the ground by scratching in soil and loose sand with its feet ( storr 1965a ) .

the rice stink bug , oebalus pugnax , is a flying insect in the shield bug family pentatomidae native to north america that has become a major agricultural pest in the southern united states .

it has been a known pest since at least the time of johan christian fabricius , who described the species in 1775 .

this study demonstrated that not all host grasses supported individuals of o . pugnax equally . oebalus pugnax preferentially moved to some host grass species more than others . singh et al . ( 2006 ) showed that different volatiles are produced from different host grass species resulting from o . pugnax feeding injury . this may help to explain why o . pugnax could be found in abundance on one host grass species relative to others .

as a graminaceous feeder , o . pugnax feeds on a broad range of grass species . in a host survey of 2011 and 2012 , 11 non - cultivated grass species were identified as important to o . pugnax in the central mississippi delta region of the usa ( awuni , 2013 ) . oebalus pugnax densities were greater on some hosts than on others ( awuni , 2013 ) . this may be a result of a feeding preference or it may come from some other basis . regardless , the choice of host grass can impact the growth and development of both nymph and adult o . pugnax . although temperature has been reported to have profound influence on the feeding performance of o . pugnax ( naresh & smith , 1983 ; rashid et al . , 2005a ) , several authors have suggested that host plant availability constitutes the most important element for o . pugnax survival , reproduction , growth , and development ( douglas & ingram , 1942 ; odglen & warren , 1962 ; naresh & smith , 1984 ; rashid et al . , 2005b ) .
studies on feeding preference are common in the ecological literature . compared to other pentatomids , limited host preference studies have been conducted on o . pugnax . naresh & smith ( 1984 ) conducted host preference studies on o . pugnax with 11 host grasses and observed that the number of adults doubled from 1 to 6 h after release across host grasses . in this study , ca . 80 % of o . pugnax adults had settled across host grasses by 4 h after release .

. . . but , in this study , these host grasses appear to support o . pugnax populations that overwinter . because of foliar insecticide sprays for o . pugnax control in rice fields , limited sampling was conducted in rice , but other research showed that rice is preferred for feeding ( awuni et al . 2014 ) . . . .

these experiments were conducted under laboratory conditions at the delta research and extension center ( drec ; stoneville , ms , usa ) , from may to july , 2012 . oebalus pugnax adults were collected from naturally occurring populations on heading wild host grasses in and around washington county , ms , with a 38 - cm - diameter sweep net ( bioquip products , rancho dominguez , ca , usa ) . oebalus pugnax were sorted after every 10 sweeps , placed in 30 × 30 × 30 - cm bugdorm cages ( bioquip ) , and transported to the laboratory . prior to the test , o . pugnax were maintained in bugdorm cages on a 10 % ( wt / vol ) sugar solution for a 12 - h period at 25 ± 2 °c , 60 ± 5 % r . h . , and l14 : d10 photoperiod . bioassays included males and females tested separately .
in the no - choice study , nymphal survival to adulthood was evaluated by expressing the number of o . pugnax second instars that survived to adulthood as a percentage of the initial number of second instars tested per host . the mean development time ( mdt , days ) of o . pugnax second instars reared to adulthood was evaluated using the formula proposed by edde & amatobi ( 2003 ) :
. . . but , in this study , these host grasses appear to support o . pugnax populations that overwinter . because of foliar insecticide sprays for o . pugnax control in rice fields , limited sampling was conducted in rice , but other research showed that rice is preferred for feeding ( awuni et al . 2014 ) . the sequence of host grass availability was important because the preferred feeding sites of o . pugnax change over time , so a succession of hosts is required for successive generations during any crop season ( panizzi 1997 , borges et al . 2011 ) . . . .
in the central mississippi delta , ryegrass was the most predominant host grass species during early spring that supported the survival , reproduction , and development of o . pugnax from overwintering ( awuni , 2013 ) . glyphosate - resistant ryegrass in the central mississippi delta ( bond & eubank , 2012 ) could be a key component in o . pugnax management because of its role in population buildup from spring into summer .
this study specifically evaluated ( 1 ) the preference of o . pugnax in free - choice tests on 11 host grass species identified in and around the central mississippi delta region , and ( 2 ) the mean development time and survival of o . pugnax second instars to adults in no - choice test on rice , dallisgrass ( paspalum dilatatum poir . ) , and junglerice [ echinochloa colona ( l . ) link ] .
in conclusion , this study provides a hierarchal host preference of o . pugnax among the principal host grasses identified in and around the mississippi rice production area . managing the growth and abundance of these host grasses around rice fields may reduce o . pugnax populations , which may reduce the need for pesticide use in rice , thereby reduce pesticide resistance , and reduce yield losses and the incidence of pecky rice in commercial rice fields . further study is recommended to examine the dispersal ability of o . pugnax and an efficient and effective strategy of herbicide use in rice , aimed at preserving the long - term mid - southern us rice production systems .
. . . ( goyal et al . 2012 ) . furthermore , the rice pest oebalus pugnax fabricius ( hemiptera : pentatomidae ) shows a high survival rate on the weed echinochloa colona , which serves as a food source ( awuni et al . 2014 ) . in some cases , weeds serve as hosts for insect vectors of viral and bacterial diseases ( eziashi et al . 2013 ) . . . .

field cage experiments were conducted in 2010 and 2011 in stoneville , ms to evaluate the impact of adult rice stink bug , oebalus pugnax ( f . ) , in two rice cultivars ( ‘cocodrie’ and ‘wells’ ) at bloom , milk , and soft dough stages of panicle development . the experiments were in a randomized complete block with 20 replications on individual rice panicles with sleeve cages and four replications on . . .

knowledge of host preference among these host grasses is important to understanding the population dynamics and movement of o . pugnax into rice fields . cueto et al . ( 2001 ) noted that feeding preference experiments are the most appropriate methods for assessing food suitability .

in the free - choice study , initial analysis examined the role of sex of o . pugnax in determining host feeding preference . because it was not a significant factor , sex was included in the model as a random effect . all analyses were conducted by test with a repeated measure statement to determine feeding time and host preference . two separate analyses were conducted . in the first analysis , all o . pugnax were included and the cage was considered one of the possible hosts . in the second analysis , only o . pugnax observed on panicles were included . each test was statistically evaluated and an overall statistical ranking was evaluated relative to junglerice . a pooled relative statistical preference rating from all experiments was then compared with junglerice on a common preference rating of all host grass species . in the free - choice analyses , post - release time ( h ) , host grass , and their interactions were included in the model as fixed effects . the replication by o . pugnax sex was included as a random effect .
the rice stink bug , oebalus pugnax ( fabricius ) ( hemiptera : pentatomidae : carpocorini ) , is an important pest of rice , oryza sativa l . ( poaceae ) , in the southern usa because of its impact on grain quality and yield ( way , 2003 ) . in general , phytophagous insects prefer to feed on host plants or plant structures that provide the greatest nutritional quality for development and reproduction ( scheirs et al . , 2005 ; molina & trumper , 2012 ) .
rice growers in the mid - south have been encouraged to approach pest problems via integrated management ( ipm ) . the development of any ipm strategy requires grower knowledge of the life history and habitat of the target pest . for example , rice fields in close proximity to pastures , sorghum fields , et cetera , may be pre - disposed to o . pugnax infestation . even before planting , a careful evaluation of the field environment would have to be assessed . removal of these host grasses at early stages in and around rice production fields mechanically , physically , or by chemical means could minimize o . pugnax infestations in rice fields . furthermore , timely herbicide and flood application to control weeds in rice production fields could prevent early attraction of o . pugnax into rice fields .

. . . in contrast , odglen and warren ( 1962 ) reported e . crus - galli as the most preferred host of o . pugnax amongst the uncultivated host grass species . in a related study , awuni et al . ( 2014 ) reported e . colona as the most preferred of the 13 host grass species in a preference and suitability tested . . . .
however , espino , way and olson ( 2007 ) found no significant difference in weight reduction in whole grains after infestation with o . pugnax . these authors believes that this can be explained by the compensatory responses of plants , which have a mechanism of tolerance to feeding of insects , and which in this case do not show a reduction in yield when injured , because when the stink bugs feed on developing grains , which are a “sinkhole” for the plant , they do not affect the “source” ( roots and foliage ) , and although the feeding of insects may have caused an increase in the number of empty spikelets , plants can offset this damage by filling the grains more or increasing the movement of photosynthesis products for spikelets that were not attacked by o . pugnax ( panda ; khush , 1995 ) .
among the major late - season pests of rice , the stink bugs of the oebalus genus ( hemiptera , pentatomidae ) , especially oebalus poecilus ( dallas 1851 ) , are insects of great economic importance to producers of rice in brazil in all cropping systems ( irrigation , flood or upland ) ( vieira ; santos ; sant´ana , 1999 ; silva ; ferreira ; vieira , 2002 ) . these pentatomids are known as stink bugs of panicles , because nymphs and adults feed mainly on this part of the plant . during the direct feeding in these structures , these insects cause quantitative and qualitative reductions in grain production ( vieira ; santos ; sant´ana , 1999 ; ferreira ; vieira ; rangel , 2002 ; fritz et al . 2008 ) .
the small rice stink bug , oebalus poecilus ( dallas ) , occurs in almost all south american countries ( becker & grazia - vieira , 1971 ; grazia - vieira & casini , 1973 ) . it feeds on developing grains of various plant species , both wild and cultivated ( albuquerque , 1991 ) , and is a major pest in irrigated rice ( gallo et al . , 2002 ) .
bioassays were prepared by excising panicles to include 2–3 cm of the main stem and the entire panicle . five excised panicles were mounted in a capped 37 . 0 - ml clear solo plastic cup ( t125 0090 solo cup , highland park , il , usa ) through holes ( 4–5 mm diameter ) created at the center of each plastic lid . solo cups were filled with water to reduce desiccation of the plant material . panicles were then assigned at random to one of the four corners of each cage . five o . pugnax adults were placed on sterile petri dishes ( 5 × 90 mm ) ( the scientific company , denver , co , usa ) at the center of each cage as released points . male and female o . pugnax adults were tested separately in five replicates , with each cage being a replicate . cages were left undisturbed during and after each period of observation .
field experiments were conducted in 2011 and 2012 at the delta research and extension center , stoneville , ms to determine the impact of duration ( days ) of o . pugnax infestation during the milk stage of panicle development with sleeve cages ( 20 x20 cm ) . the study was a randomized complete block with 2 ( cultivars ) by 5 ( days ) factorial arrangement on one insect density per panicle with . . . [ show full abstract ]
similarly , when comparing the results of empty spikelets found in our study with other research , it can be seen that there may be a pattern in the effects caused by stink bugs feeding on rice panicles . the percentage of empty spikelets in the caryopsis stage reached 41 % , 42 % and 83 % for infestations with one , two and four o . poecilus adults , respectively . a similar pattern was reported by patel , stout and fuxa ( 2006 ) in evaluating the damage caused by o . pugnax females wherein infestations made one day after anthesis / caryopsis caused infestation with one stink bug of about 40 % of empty spikelets and up to 60 % of damage for infestations with two insects . these authors also observed that with panicle development , the percentage decreased to less than 10 % in both infestations . other studies , also with o . pugnax , by espino et al . ( 2007 ) and espino and way ( 2007 ) found a higher percentage of empty spikelets in infestations accomplished in the early stages of development of panicles .
preference of o . pugnax among the 11 host grass species was not significantly influenced by the sex * host * post - release time ( h ) interaction in any of the four tests : f 12 , 160 = 0 . 14–0 . 47 , p = 0 . 93–1 . 0 . the main effect of sex was not significant in the four tests : f 1 , 160 = 0 . 03–2 . 96 , p = 0 . 09–0 . 85 . therefore , sex was moved to being a random effect in the model and the data were re - analyzed . there was a significant post - release time * host grass interaction for all four tests when o . pugnax adults found on cage walls were included in the analysis as a possible host : f 16 , 80 = 2 . 24–7 . 86 , all p < 0 . 01 . because all four tests followed the same pattern of results , the data were combined for re - analysis . there was a significant host * post - release time interaction of the combined test analysis ( f 4 , 309 = 51 . 14 , p < 0 . 01 ) .
the no - choice test demonstrated that rice was a more suitable host over junglerice and dallisgrass , consistent with previous observations . nymphal survival was higher and mean development time shorter when reared on rice . rashid et al . ( 2005b ) reported longer mean development time of o . pugnax reared on dallisgrass compared to rice flour diet and barnyardgrass . hamm ( 2011 ) reported shorter mean development time and greater body weight when nymphs were reared from first instars to adults on rice than on barnyardgrass or amazon sprangletop , leptochloa panicoides ( j . presl ) hitchc . aside from host plants also temperature can impact o . pugnax development . nymphs have been reported to survive better at 30 °c when fed grain sorghum , sorghum bicolor ( l . ) , compared to rice ( naresh & smith , 1983 ) . in a previous experiment , development times ranged from 17 to 37 days at 21 to 29 °c , respectively ( rashid et al . , 2005a ) . similarly , in the current experiment the mean development times from second instar to adult at 25 ± 1 °c were 17 , 18 , and 20 days on rice , junglerice , and dalligrass , respectively .
in 2002 , the arrival period of adults at the hibernation site began in the second fortnight of april . this delay in relation to the preceding year was due to a late rice seeding period . movement into hibernation sites at the end of summer , and out of it in the spring , has been observed for other heteroptera such as n . viridula ( kiritani et al . , 1962 ) , o . pugnax ( nilakhe , 1976 ) , b . l . leucopterus ( negron & riley , 1991 ) , and e . heros ( panizzi & vivan , 1997 ) .
the hibernation period of o . poecilus lasted between 7 and 8 months , close to that registered for o . pugnax in the northern hemisphere ( nilakhe , 1976 ) . the duration of the hibernation period in pentatomidae may be variable . aner ( 1991 ) pointed out , for the same latitude as that of the present study , that edessa meditabunda ( de geer ) and t . limbativentris go through a 4 and 10 month hibernation period , respectively . panizzi & vivan ( 1997 ) demonstrated that e . heros hibernation in londrina , pr , brazil , lasts 6 months . the differentiated hibernation period may also be related to a species feeding behavior .
thus , our work is the basis for the conduction of similar studies with other stink bug species that feed on rice crop , including researches with new pentatomidae species that have recently been reported in this region on upland rice ( krinski ; foerster , 2017b ; krinski ; foerster ; grazia , 2015 ) . furthermore , studies should be conducted , for example , to check whether the oebalus nymphs can cause the same damage as the adults , and also whether males and females cause similar damage , as studied in other species ( espino ; way ; olson , 2007 ; espino ; way , 2007 ) .
although there are many studies reporting the damage of several species of oebalus , most were conducted in irrigated rice ( ferreira ; vieira ; rangel , 2002 ; ferreira ; barrigossi , 2006 ) . moreover , these studies usually consider only the number of spikelets produced ( filled and empty ) and the weight of the grains after infestation with insects , and do not consider qualitative damage such as damaged kernels ( pecky , atrophied and chalky ) and broken grains ( grits ) . thus , are incipient the info of damage that this stink bug can cause in upland rice , mainly in new agricultural areas , for example in crops grown in pará state , in the amazon rainforest region .
in our study , the total number of spikelets showed no statistical difference in infestations between all reproductive growth stages , as also observed by ferreira , vieira and rangel ( 2002 ) , who conducted research on infestation of o . poecilus and o . ypsilongriseus in ten and five genotypes of irrigated rice , respectively . this pattern was also observed by ferreira and barrigossi ( 2006 ) in damage evaluating of o . poecilus in panicles of 39 genotypes of irrigated rice , and also in a study by espino , way and olson ( 2007 ) that verified the damage caused by o . pugnax . this result was as expected , since the number of spikelets per panicle produced by the plant is due to genetic factors of the plant itself , and also the fact that experiments with insect infestations are usually carried out when the panicles have been liberated by the plant .
the works that have investigated the effects of feeding various species of stink bugs of panicles report that the intensity of the attack of insects is related to the stage of panicle development . thus , losses resulting from such attacks in different genotypes and rice cultivars are probably variable . moreover , in our study we report the damage by stink bugs of the oebalus genus ; however , several other species of stink bugs are considered pests of panicles in rice production areas worldwide , with prominence for the genera aspavia , cletus , eysarcoris , leptocorisa , mictis , mormidea and nysius , among others ( ewete ; olagbaju , 1990 ; pantoja et al . , 1995 ; ferreira ; barrigossi ; vieira , 2001 ; ishizaki ; yasuda ; watanabe , 2007 ; ishizaki ; tetsuya ; watanabe , 2008 ) .
ferreira , vieira and rangel ( 2002 ) showed that a reduction of approximately 30 % for infestation with o . ypsilongriseus and 38 % for o . poecilus occurred early in the milky stage , which is a result similar to that seen in our work , which showed a decrease in grain mass of approximately 33 % , however for a later growth stage of the panicle . silva , ferreira and vieira ( 2002 ) showed a more discreet reduction of up to 11 . 5 % in grain mass after infestation with o . poecilus and o . ypsilongriseus performed early in the milky stage in upland rice . patel , stout and fuxa ( 2006 ) obtained data similar to that of silva , ferreira and vieira ( 2002 ) for the mass reduction caused by o . pugnax , reaching a maximum of 11 % after infestation with two adult insects . these authors also report that the first 12 days after anthesis are the most critical for damage related to the reduction of grain weight .
oebalus poecilus ( dallas ) is an important pest affecting irrigated rice in rio grande do sul , brazil . it hibernates during the coldest months of the year in refuges such as bamboo litter . this study examined o . poecilus hibernation to determine the causes of mortality during this period . the study was conducted in a 140 m 2 bamboo plantation located in a rice - growing area in eldorado do sul county ( 30° 02 s and 51° 23 w ) , rs . during june 2000 to april 2002 , 63 samples of litter were taken in weekly or fortnightly intervals , and the number of bugs recorded in the laboratory . the arrival at the hibernation site ( bamboo litter ) began in the first fortnight of march , and was completed in the beginning of may . o . poecilus left this refuge from middle october to the end of december . parasitism by tachinid flies and beauveria bassiana ( bals . ) vuill . fungus were the most important mortality factors .
oebalus poecilus ( dallas ) é praga importante do arroz irrigado no rio grande do sul , brasil . este inseto hiberna durante os meses mais frios em refúgios como o folhedo de bambu . este estudo objetivou elucidar a hibernação de o . poecilus e determinar as causas de mortalidade durante este período . o estudo foi realizado em um bambuzal com cerca de 140 m 2 , situado em área orizícola , em eldorado do sul ( 30° 02 s e 51° 23 w ) , rs . de junho / 2000 à abril / 2002 , foram realizadas 63 amostragens de folhedo , em intervalos semanais ou quinzenais e o número de percevejos registrado em laboratório . a entrada no refúgio de hibernação ( folhedo de bambu ) iniciou na primeira semana de março , completando - se no início de maio . o . poecilus abandonou o refúgio da metade de outubro até o final de dezembro . o parasitismo por mosca ( taquinídeos ) e o fungo beauveria bassiana ( bals . ) vuill . foram os principais fatores de mortalidade .
oebalus poecilus ( dallas 1851 ) é uma das espécies de percevejos de grande importância econômica para os produtores de arroz no brasil em sistemas de cultivo irrigados , de inundação ou de terras altas . estes pentatomídeos são conhecidos como percevejos das panículas , porque ninfas e adultos alimentam - se principalmente dessas estruturas . o ataque deste percevejo resulta em grãos manchados , massa inferior , redução germinativa e grãos deformados . considerando isso , o objetivo deste estudo foi avaliar as perdas quantitativas e qualitativas na cultivar comercial de arroz de terras altas ( variedade cambará ) , submetidas a diferentes níveis de infestação de percevejos de panículas , o . poecilus , em diferentes estágios de crescimento reprodutivo das plantas de arroz . os resultados mostram que em arroz de terras altas ( variedade cambará ) , os grãos de arroz são suscetíveis a danos quantitativos ( número e peso ) e qualitativos ( grãos manchados , atrofiados , gessados e quebrados ) , durante todo o desenvolvimento da panícula . no entanto , quando os insetos se alimentam durante os estágios de antese / cariopse e leitosa causam percentual significativamente maior de grãos vazios ( até 83 % ) do que quando se alimentam de grãos durante as fases posteriores do desenvolvimento da panícula . esta característica foi também observada para a redução de peso dos grãos . esta informação pode beneficiar os produtores e outros pesquisadores , permitindo que concentrem os esforços de monitoramento de o . poecilus em fases mais suscetíveis ao ataque deste inseto . também serve de base para a tomada de decisão sobre quando e quais medidas de controle devem ser realizadas , a fim de controlar os percevejos das panículas .
we are receiving phone calls from growers , consultants , and county agents about the huge surge of stink bugs coming into heading wheat fields . in most cases , it is predominantly rice stink bug but in a few cases and even in fields with rice stink bug there are also brown stink bugs .
these stink bugs appear to be across the entire wheat acreage of the state and are showing up as the wheat begins heading . the threshold in arkansas has always been one per head , however , it is interesting to note that angus catchot , extension entomologist for mississippi state university , quoted a threshold of 1 stink bug per 5 - 10 heads which is 10 - 20 % infestation ( see www . mississippi - crops . com ) . while lower than arkansas , that’s still a lot of stink bugs . also , it must be noted that wheat prices are very high…either way , it’s safe to say that it takes a lot of stink bugs to cause damage in wheat .
the susceptible stages of wheat to stink bug are the milk and soft dough stage . prior to and later ( hard dough ) stages are safe from damage by stink bugs . more importantly , these infestations in wheat may lead to stink bug issues in other crops . therefore , you should : 1 ) scout seedling corn very closely for stink bugs . stink bugs can be very damaging to seedling corn . severe damage has been observed in corn in recent years . corn should be scouted very closely due to the high levels of stink bugs currently present in fields . 2 ) since stink bug populations appear to be building rapidly , scout rice closely when it begins to head . with reduced rice acreage that means more stink bugs looking for rice when the time comes… .
numbers of stink bugs are much higher on the edges of the field . in our observations stink bug numbers can be high at the edge of the field , yet when you get into the field 50 - 100 feet , the numbers fall off drastically – most of the time 75 % or more . so , while you may be at threshold on the edges you may be well below threshold on the majority of the field . if you think an insecticide application is warranted , strip treating the edges may be the best choice . only good scouting will determine that .
many of you may be applying a fungicide right now and want to just “stick in some pyrethroid . ” be sure to think about the cost effectiveness of that application to help make the right decision . others may be considering “spraying now to kill them before they get to my rice or corn . ” this is not a good ipm approach as it’s not effective , nor recommended to “spray now” for what may or may not happen in the future .
stink bug , especially rice stink bug , is an extremely mobile insect . we have often seen cases where fields of wheat that had large stink bug numbers one day had virtually none just 2 - 3 days later , even though no insecticide was applied to the field . point being , if you decide to treat , before the application goes out , you might want to check and make sure the stink bugs are still there . we don’t understand what makes stink bugs pick up and move “en masse” but know that it does happen .
if treatment is warranted , make sure that the pyrethroid of choice is one that is labeled for use in wheat .
