Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome?

open access: yesInsect Science, EarlyView.
We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not associated with changes in abundance/composition/diversity of the insect's bacterial microbiota, but additional endophyte effects on this microbiota cannot be

Understanding biological control function and trophic interaction dynamics of an artificially released predatory bug by DNA metabarcoding

open access: yesInsect Science, EarlyView.
This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.

Comparative Morphology and Morphometry of Six Biotypes of Bemisia tabaci (Hemiptera: Aleyrodidae) from China

open access: yesJournal of Integrative Agriculture, 2013
Morphology and morphometry of six biotypes (B, Q, Cv, ZHJ-1, ZHJ-2 and ZHJ-3) of Bemisia tabaci (Gennadius) from China on cotton plants were studied by using microscopes. Nymphal body sizes and characters were measured and observed, especially on the 4th

Identification of a self-regulatory pheromone system that controls nymph aggregation behavior of rice spittlebug Callitettix versicolor

open access: yesFrontiers in Zoology, 2015
BackgroundNymphs of many spittlebug species are known to aggregate in one spittle mass, a behavior which greatly benefits the survival of the developing nymphs.

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Life cycle and reproductive parameters of Clerada apicicornis signoret (Hemiptera: Lygaeidae) under laboratory conditions

open access: yesMemorias do Instituto Oswaldo Cruz, 2001
The life cycle of Clerada apicicornis was determined under laboratory conditions. Mean development times in days were: egg 27.2, nymph I 12.5, nymph II 12, nymph III 13.4, nymph IV 16.4, nymph V 26.

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

open access: yesInsect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.
