title: Data from: Sex pheromones from <em>Linyphia triangularis</em> (Araneae: Linyphiidae) and <em>Aphidoletes aphidimyza</em> (Diptera: Cecidomyiidae) are promising attractants for <em>Aphidoletes aphidimyza</em> (Diptera: Cecidomyiidae)

description: Although Aphidoletes aphidimyza (Rondani) is a predator of aphids, its
 biocontrol efficacy depends largely on oviposition behavior. Previous
 studies have shown that spider webs can attract A. aphidimyza and enhance
 its oviposition. It has been hypothesized that sex pheromones from spider
 webs and A. aphidimyza itself may affect its mating and oviposition, but
 this remains unconfirmed. In our study, we selected
 (2R,7S)-diacetoxytridecane (sex pheromone of A. aphidimyza),
 (R)-3-hydroxybutyric acid (sex pheromone of Linyphia triangularis
 (Clerck)), and a mixture of these pheromones (at a 10:1 concentration
 ratio) to investigate their overall response on A. aphidimyza in terms of
 electroantennogram, behavior, fecundity, attraction, and aphid control.
 Our results indicated that these pheromones elicited antennal responses in
 A. aphidimyza. Specifically, (2R,7S)-diacetoxytridecane significantly
 attracted males, while (R)-3-hydroxybutyric acid significantly attracted
 females; their mixture attracted both sexes. These compounds did not
 affect oviposition and lifespan of A. aphidimyza. The pheromone mixture
 attracted significantly more A. aphidimyza than the control group. The
 number of aphids in the mixture group began to decline one day earlier
 than that in the control group and ultimately achieved a 100% control
 effect against aphids in a greenhouse. Our findings provide evidence for
 further exploration of the relationship between L. triangularis and A.
 aphidimyza. The studied pheromone blend shows potential as an attractant
 for A. aphidimyza, which could enhance aphid biological control in
 greenhouses.

 data and file structure In this study, we investigated the response of *A.
 aphidimyza* to sex pheromones by performing five key experiments: (i) the
 EAG response of *A. aphidimyza* to the sex pheromones of *L. triangularis
 and* *A. aphidimyza*; (ii) the behavioral responses of *A. aphidimyza* to
 sex pheromones from *L. triangularis* and *A. aphidimyza* and their
 mixture; (iii) the effects of sex pheromones from *L. triangularis and A.
 aphidimyza*, and their mixture on the oviposition and lifespan of *A.
 aphidimyza*; (iv) the bidirectional selection of *A. aphidimyza* to mixed
 pheromone; and (v) the control effect of the mixed pheromone attractant
 from *A. aphidimyza* on *A. craccivora* in a greenhouse. ### Figure_1.csv
