Title : 
 Dataset : Risk assessment requires several bee species to address species - specific sensitivity to insecticides at field - realistic concentrations 

 Abstract : 
 This dataset includes measurements of individual bee mortality , weight and behavior collected under laboratory conditions in six trials over two years . Individuals of seven different bee species were exposed to the plant protection product Karate ® Zeon ( containing the pyrethroid lambda - cyhalothrin ) at a field - realistic application rate of 0.075 L product / ha in a professional spray chamber . In addition , we applied either water as a control or dimethoate as a toxic reference to bee individuals of all species . In total , we tested 409 Apis mellifera , 385 Bombus terrestris , 383 Osmia bicornis , 139 Osmia cornuta , 140 Megachile rotundata , 105 Andrena vaga , and 103 Colletes cunicularius individuals . Bee individuals were placed into cages of 10 or 5 individuals depending on the species , and the mean individual weight of all non - Apis bees was measured as the total bee weight per cage devided by the number of bees in this cage . Bees were exposed and afterwards monitored over a period of 96 hours at pre - defined time intervals ( 2 , 4 , 24 , 48 , 72 and 96 hours after application ) . At each time interval , we recorded their status ( dead or alive ) and behavioral abnormalities ( moribund , cramps , apathy , affected [ including restless , vertigo , uncoordinated and dorsal position ] ) . Further methodological and analytical details are described in the associated paper by Jütte et al . : Risk assessment requires several bee species to address species - specific sensitivity to insecticides at field - realistic concentrations . Scientific Reports , 2023 . The dataset comprises four tables . Table " Mortality " includes a row for each individual tested with lambda - cyhalothrin ( 716 individuals ) or water ( 708 individuals ) stating its species identity , the number of trial and cage it was placed in , the treatment it was exposed to , its status and at which time interval this status was observed . Table " Dimethoate " includes a row for each individual tested with the toxic reference dimethoate ( 240 individuals ) stating its species identity , the number of trial and cage it was placed in , its status and at which time interval this status was observed . Table " Behavior " includes a row for each cage that contained bee individuals treated with lambda - cyhalothrin ( 126 cages ) or water ( 125 cages ) at each time interval . This table states the species identity , the number of trial and cage , the treatment , the time interval , and the number of bee individuals in this cage at this time , which were dead , were alive , showed moribund behavior , showed apathy , showed cramps or showed an affected behavior , which could be any of four abnormal behaviors ( restlessness , vertigo , dorsal position , uncoordinated movement ) . Table " Weight " includes a row for each cage that contained bee individuals treated with lambda - cyhalothrin ( 126 cages ) or water ( 125 cages ) at each time interval . This table states the species identity , the number of trial and cage , the treatment , the number of bee individuals in this cage , and the mean weight of a bee individual in this cage .
