Predatory ants are crucial biological control agents in agroecosystems, but such activity may vary during dry and wet seasons. In this study, we investigated whether the mortality caused by predatory ants to the larvae of Ascia monuste orseis (Godart) varies due to the effects of dry and wet seasons. We performed a field experiment repeated eight t...

The Japanese beetle, Popillia japonica Newman, is an invasive insect to the United States that feeds on turfgrass roots as a larva and the foliage, flowers, and fruit of many major ornamental and agricultural crops, such as apple, as an adult. Despite its generalist feeding behavior, P. japonica shows preferences for certain plant species and culti...

The optimal defense theory stipulates that a plant prioritizes the defense of young tissue against herbivory, which may affect the spatial distribution of the attacking insect and its impact on plant performance. In this study, we evaluated the feeding and oviposition site preferences of the citrus mealybug, Planococcus citri (Risso, 1813) (Hemipte...

BACKGROUND In precision integrated pest management, management tactics are implemented only where and when needed, by identifying the sites where the pest population has reached economic thresholds. Tomato, Solanum lycopersicum (Linn.), is a vegetable cultivated worldwide, but its production is reduced by insect pests such as the whitefly, Bemisia...

In this study, we evaluated the causes of mortality in immature stages of Ascia monuste orseis Godart 1918 (Lepidoptera: Pieridae) over each of four seasons, for 2 years, on an experimental cabbage plot using life tables. We addressed two key questions: (1) Do the mortality rates caused by a factor vary by season? And (2) how does the local weather...
