“…2E–G) is a cosmopolitan moth which flies nocturnally and larvae feed on several genus of Fabaceae 39 . In Brazil, it is known as one of the main pest responsible for the damage in the production of beans ( Phaseolus vulgaris ) of Rio Grande do Sul, due to the damage caused to seeds 53 . E. zinckenella was reported to feed in five species of Crotalaria : C. pallida , C. incana , C. micans , C. zanzibarica (= C. trichotoma ), C. vitelina 40,54 (JR Trigo, pers.…”

In order to evaluate the geographic mosaic theory of coevolution, it is crucial to investigate geographical variation on the outcome of ecological interactions and the functional traits which dictate these outcomes. Plant populations are attacked by specialist and non-specialist herbivores and may have different types of chemical and biotic defences. We investigated geographical and seasonal variation in the interaction between the plant Crotalaria pallida and its two major herbivores (the specialist Utetheisa ornatrix and the non-specialist Etiella zinckenella). We first showed that attack by the two herbivores and a chemical and a biotic defence vary greatly in time and space. Second, we performed a common garden experiment that revealed genetic variation among populations in herbivore resistance and a chemical defence, but no genetic variation in a biotic defence. Third, we sampled 20 populations on a much larger geographical scale and showed great variation in attack rates by the two herbivores and a chemical defence. Finally, we showed that herbivory is not correlated with a chemical defence in the 20 field populations. Our study shows that to understand the evolution of ecological interactions it is crucial to investigate how the outcome of the interaction and the important species traits vary geographically and seasonally.

“…One limabean pod borer larva can feed on more than one seed in a pod (Talekar and Lin 1994). Also, Melo and Silveira (1998) quantified the damage. Our study was carried out to evaluate the T. evanescens or Neem for controlling this insect compared with a recommended insecticide.…”

Field studies were conducted at Shandweel Agricultural Research Station (Sohag Governorate) to evaluate the integration program which include varietal tolerancy of three cowpea cultivars (Kaha-1, Cream-7 and Dokki-126) against the infestation with E. zinckenella, also, the effect of Trichogramma evanescans, the use Neem extract and Lannate insecticides.The release of egg parasitoid T. evanescans at rat of 30.000 wasps/fed. in cawopea fawned significantly with the Neem in the infested pods and infested seeds. The %infested pods clearly decreased after application of these considered treatments with about 69.21, 75.96 and 75.13% when used Trichogramma wips, but these results in Neem about 57.50, 54.55 and 64.93%, respectively, however, the results were about 72.62, 74.18 and 73.56%, respectively when used Lannate compared with the control, in the first season. Insignificant differences in %infested pods were observed between the three cultivars. No significant differences were found in percent reduction of %infested pods, infested seeds and number of larvae/pods between cowpea plants treated with Trichogramma and those treated with Lannate insecticide. Could be recommended relesease of egg parasitoid T. evanescens to control agents against E. zinckenella.Correlation studies showed highly negative significant among percentage infected pods and seeds traits and each of number of pods/plant, weight of pods/plant, weight of seeds/plant, 100-seeds weight and dry seeds yield/fed., but, it was positive insignificant with number of branches/plant, in the both seasons.

[71][72][73] Interestingly, we found that, in 2015, populations of spider mites were negatively correlated with populations of ladybeetles, hoverflies, and predaceous pentatomids. In fact, spider mites are suitable prey for many coccinellids 74,75 and syrphids, 76 but we found no reports in the literature that predatory stink bugs can utilize spider mites as a prey item.…”
