Behavior, development, and predation of podisus nigrispinus (Hemiptera: Pentatomidae) on spodoptera frugiperda (Lepidoptera: Noctuidae) fed transgenic and conventional cotton cultivars
(2014-01-01)
The association of insect-resistant plants with biological control is important in integrated management to reduce the density of pests below the economic injury level. The behavior, development, and predation of Podisus ...
Constituintes químicos e atividade inseticida dos extratos de frutos de Trichilia elegans E T. catigua (Meliaceae)
(Sociedade Brasileira de Química, 2009)
Phytochemical investigation of the fruits extracts of Trichilia elegans and Trichilia catigua (Meliaceae) has led to the identification of the limonoids 11β-acetoxyobacunone, cedrelone, methylangolensate and epimeric ...
Maternal Care by the Earwig Doru lineare Eschs. (Dermaptera: Forficulidae)
(2013-09-01)
We performed laboratory experiments to study maternal care in Doru lineare Eschs. (Dermaptera: Forficulidae), a predator of the maize pest Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae). Females laid 29.7 ± 8.43 ...
On-plant larval movement and feeding behavior of fall armyworm (Lepidoptera: Noctuidae) on reproductive corn stages
(Oxford University Press, 2015-10-17)
Spodoptera frugiperda J.E. Smith (fall armyworm) is considered one of the most destructive pests of corn throughout the Americas. Although this pest has been extensively studied, little is known about its larval movement ...
Long-Term Mass Rearing Impacts Performance of the Egg Parasitoid Telenomus remus (Hymenoptera: Platygastridae)
(2020-01-01)
The effects of long-term laboratory rearing on the performance of Telenomus remus Nixon (Hymenoptera: Platygastridae), an egg parasitoid of Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), were investigated by ...
Social wasps are effective biocontrol agents of key lepidopteran crop pests
(2019-11-06)
Biocontrol agents can help reduce pest populations as part of an integrated pest management scheme, with minimal environmental consequences. However, biocontrol agents are often non-native species and require significant ...
Influence of fall armyworm previous experience with soybean genotypes on larval feeding behavior
(Springer, 2017-02-01)
Previous experience on host plants can modify insect feeding behavior. Because insect habituation and induction of preference to host plants are variable across species of plants and insects, it is necessary to investigate ...
