Sharpening our understanding of saber‐tooth biomechanics

The Anatomical Record, EarlyView.
Abstract Saber‐teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber‐toothed taxa employed a distinct biting strategy compared to conical‐toothed carnivores, like the lion, the precise mechanics and variability of this ...

Field Control Effect of Telenomus remus Nixon and Trichogramma chilonis Ishii Compound Parasitoid Balls against Spodoptera frugiperda (J. E. Smith)

Insects
Although the release of egg parasitoids has proven to be an effective strategy for the control of the fall armyworm (FAW), a single egg parasitoid, however, has exposed some deficiencies in practice, and it is worthwhile to explore whether the ...

Trichogramma: an egg parasitoid of crop pests

Bhartiya Krishi Anusandhan Patrika, 2018
Use of insecticides to manage the emerging pest problems in the different crop being taken by farmers in their field. Today, due to indiscriminate use of insecticide, the agriculture produces getting contaminated and traced in food channel. For the reason, many farmers moving towards organic farming to produce pesticide free foods.

Embryogenesis in Myrmicine Ants Combines Features of Short Germ‐Band Development With a Progressive Mode of Segmentation

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Different insect species exhibit remarkable diversity in the developmental trajectories from fertilized eggs to hatching larvae. For three myrmicine ant species, we observe a novel combination of a developmental features: small embryonic primordia, a mode of embryogenesis termed short/intermediate germ‐band development, and progressive establishment of

Multitrophic interactions: How plant defense is amplified by entomopathogenic nematode‐infected cadavers

New Plant Protection, EarlyView.
Entomopathogenic nematode‐infected cadavers trigger plants to release volatile organic compounds that deter herbivores, attract parasitic wasps, and boost defense responses, highlighting their potential for sustainable pest management. Abstract Grasping the dynamics between plants and herbivores, as well as the defenses triggered by insects, may hold ...

First record of Gonatocerus litoralis (Haliday) (Hymenoptera: Mymaridae) from Anoplotettix putoni Ribaut (Hemiptera: Cicadellidae)

Journal of Entomological and Acarological Research, 2013
The mymarid Gonatocerus litoralis (Haliday) is recorded for the first time as an egg parasitoid of the leafhopper Anoplotettix putoni Ribaut. A study of the main morphological characters shows unusual variation in distribution of the multiporous plate ...
