Oviposition choice by soybean looper, Pseudoplusia includens (Walker), of soybean and cotton in two phenological stages was tested in field cages to determine relative oviposition preference for these two crops in a situation similar to early- to mid-season cropping conditions in Mississippi. Moths were released into field cages enclosing four contiguous rows for each of two treatments, and egg density per m of row was determined after the second night. Test 1 paired blooming cotton (planted 25 May) with either blooming (23 June) or vegetative (11 July) soybean. Relative to blooming cotton with 81.1% canopy closure, blooming soybean with 78% canopy closure received 2.6-fold greater oviposition, while vegetative soybean with 41% canopy closure received only 0.24-times the eggs as blooming cotton. Test 2 compared oviposition on the two soybean classes in the absence of cotton. Here, 11.2-fold more eggs were oviposited on blooming soybean than on vegetative soybean. Test 3 paired blooming soybean with either blooming or pre-bloom cotton (planted 23 June). Relative to soybean, the pre-bloom cotton with 68.7% canopy closure received 1.6-fold more eggs than blooming cotton, although neither cotton treatment received as many eggs as blooming soybean. This study suggests that the importance of cotton as a host of soybean looper declines as the crop growing season advances.

Chrysodeixis Includens

The objective of this work was to evaluate bean genotypes for resistance to soybean looper (Chrysodeixis includens). Initially, free-choice tests were carried out with 59 genotypes, divided into three groups according to leaf color intensity (dark green, light green, and medium green), in order to evaluate oviposition preference. Subsequently, 12 genotypes with high potential for resistance were selected, as well as two susceptible commercial standards. With these genotypes, new tests were performed for oviposition in a greenhouse, besides tests for attractiveness and consumption under laboratory conditions (26±2ºC, 65±10% RH, and 14 h light: 10 h dark photophase). In the no-choice test with adults, in the greenhouse, the 'IAC Jabola', Arcelina 1, 'IAC Boreal', 'Flor de Mayo', and 'IAC Formoso' genotypes were the least oviposited, showing antixenosis-type resistance for oviposition. In the free-choice test with larvae, Arcelina 4, 'BRS Horizonte', 'Pérola', H96A102-1-1-1-52, 'IAC Boreal', 'IAC Harmonia', and 'IAC Formoso' were the less consumed genotypes, which indicates antixenosis to feeding. In the no-choice test, all genotypes (except for 'IAPAR 57') expressed moderate levels of antixenosis to feeding against C. includens larvae.

AbstractGiven the new spread and potential damage of the fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in Asia, it has become imperative to understand the development biology of this invasive species on selected vegetable crops in newer geographical regions. In this study, we investigated the ovipositional preference of FAW females on different host plants, under choice- and non-choice tests. In addition, using the age-stage, two-sex life table theory, we assessed the performance of immature FAW individuals fed and reared on selected vegetable crops to get information related to development time, survival, reproduction and longevity. Fall armyworm females had an oviposition preference on maize compared to other vegetable crops, including cabbage and soybean, and reluctance for tomato, which was confirmed during the choice and non-choice tests. In contrast to the oviposition preference, our results also suggest that despite low preference for cabbage, soybean, and tomato, these crops seemed to provide a high benefit for an appropriate offspring performance, exceeding in some cases the benefits from a maize-based diet. Information from this study was discussed in terms of FAW ecology and how female’s decision affects their reproductive fitness, and the survival and performance of its offspring.
