Suppression of hop looper (Lepidoptera: Noctuidae) by the fungicide pyraclostrobin.
The hop looper, Hypena humuli Harris, is a reemergent pest of hop that often requires treatment to mitigate crop damage. In 4 yr of field trials, plots treated with fungicides were observed to sustain less hop looper defoliation compared with nontreated plots. Further investigation revealed that abundance of hop looper and associated defoliation were reduced when the fungicide pyraclostrobin wa...
متن کاملLespesia melloi sp. nov. (Diptera: Tachinidae) from Brazil, a Parasitoid of Xanthopastis timais (Lepidoptera: Noctuidae)
A new species of the New World genus Lespesia, Lespesia melloi SP NOV: (Diptera: Tachinidae), is described from southeastern Brazil. The species is reported here as a parasitoid of Xanthopastis timais (Cramer, 1782) (Lepidoptera: Noctuidae). The caterpillars of this noctuid feed on leaves and bulbs of amaryllis (Amaryllidaceae) in Brazil.
متن کاملEvolution and manipulation of parasitoid egg load.
In proovigenic parasitoids such as Leptopilina boulardi, the female emerges with a limited egg load and no further eggs are produced during its adult life. A female thus runs the risk of exhausting this limited supply of eggs before the end of her life. Given that the production of an egg is costly, what is the evolutionarily stable egg load at emergence? This question has attracted a lot of at...
متن کاملLaboratory Biology of Chetogena Scutellaris (diptera: Tachinidae), a Parasitoid of Noctuidae, Reared on Fall Armyworm and Cabbage Looper
The tachinid parasitoid Chetogena scutellaris (Wulp) was reared from southern armyworm, Spodoptera eridania (Cramer), a new host record. When reared in cabbage looper, Trichoplusia ni (Hübner), (a new host) and in fall armyworm, Spodoptera frugiperda (J. E. Smith), in the laboratory, C. scutellaris developed successfully ca. 30% of the time. Success of parasitism depended on the numbers of eggs...
متن کاملParasitoid-induced cellular immune deficiency in Drosophila.
L. heterotoma females inject VLPs along with their eggs into the hemocoel of the Drosophila larva. The VLPs destroy lamellocytes that are potentially harmful for the parasite eggs, but the other types of host hemocytes retain their functions. The parasitized third instar Drosophila larvae continue to grow and pupariate, showing no outward adverse effects. Minimum disruption to the growth and de...
