LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

Insect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

New resistance mechanism in Helicoverpa armigera threatens transgenic crops expressing Bacillus thuringiensis Cry1Ac toxin

, 2005
In Australia, the cotton bollworm, Helicoverpa armigera , has a long history of resistance to conventional insecticides. Transgenic cotton (expressing the Bacillus thuringiensis toxin Cry1Ac) has been grown

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Species-specific evolution of lepidopteran TspC5 tetraspanins associated with dominant resistance to Bacillus thuringiensis toxin Cry1Ac

Journal of Integrative Agriculture
Transgenic crops producing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) have proven to be highly effective in managing some key pests.

Impact of Host and Food Availability on Life‐History Traits in Six Egg Parasitoid Species of the Genus Trichogramma

Entomologia Experimentalis et Applicata, EarlyView.
In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

A chromosome-level haplotype-resolved genome assembly of oriental tobacco budworm (Helicoverpa assulta)

Scientific Data
Oriental tobacco budworm (Helicoverpa assulta) and cotton bollworm (Helicoverpa armigera) are two closely related species within the genus Helicoverpa. They have similar appearances and consistent damage patterns, often leading to confusion. However, the

The migration systems of Helicoverpa punctigera (Wallengren) and Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) in Australia [PDF]

, 2015
The contemporary view of insect migration is one of a behaviourally distinct form of movement that is an adaptation to temporary habitats. Migratory insects are characterised by a syndrome of behavioural and physiological traits that promote migration.

Development of PCR, LAMP and HRM‐Based Molecular Species Diagnostic Tools for Identifying Four Agricultural Pests in the Genus Helicoverpa (Lepidoptera: Noctuidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Within the subfamily Heliothinae, the genus Helicoverpa comprises several highly destructive agricultural pests, including H. armigera, H. assulta, H. punctigera and H. zea. These species cause significant global crop losses due to their wide host range, long‐distance migratory behaviour, and potential for interspecific hybridization.
