The hibiscus mealybug, Maconellicoccus hirsutus Green, was first reported in the Caribbean in 1994 in Grenada. This was the first record of the insect as a major pest in the New World. By the beginning of 2001, the pest had spread to over 25 territories from Guyana and Venezuela in the South to Bahamas in the North. The pest has also extended its distribution to Central America (Belize) and Nor...

Based on the importance of using low-risk compounds to protect beneficial agents, present study evaluated acute toxicity lethal and sublethal concentrations insecticides thiacloprid, pyriproxyfen, chlorantraniliprole adults Aphelinus mali (Haldeman), main parasitoid woolly apple aphid, Eriosoma lanigerum (Hausmann). Similarly, acetamiprid, buprofezin, cyantraniliprole were Acerophagus flavidulu...

Predatory coccinellid, Cryptolaemus montrouzieri Mulsant is an important biological agent in citrus orchards. The effect of six treatments included: two types mineral oils, EC and mayonnaise at the concentration 15 ml/L, buprofezin 0.75 buprofezin+EC oil 0.5+5 insecticidal soap palizin 2.5 water as control were investigated on functional numerical responses C. under laboratory conditions. exper...

Recently, several invasive mealybugs (Hemiptera: Pseudococcidae) have rapidly spread to Asia and have become a serious threat to the production of cotton including transgenic cotton. Thus far, studies have mainly focused on the effects of mealybugs on non-transgenic cotton, without fully considering their effects on transgenic cotton and trophic interactions. Therefore, investigating the potent...

We assessed the nontarget effects of ultra-low-volume (ULV) aerial adulticiding with two newwater-based, unsynergized pyrethroid formulations, Aqua-K-Othrine (FFAST antievaporant technology, 2% deltamethrin) and Pesguard S102 (10% d-phenothrin). A helicopter with GPS navigation technology was used. One application rate was tested per formulation that corresponded to 1.00 g (AI)/ha of deltamethr...

Abstract Background The ladybird beetle Cryptolaemus montrouzieri Mulsant, 1853 (Coleoptera, Coccinellidae) is used worldwide as a biological control agent. It predator of various mealybug pests, but it also feeds on alternative prey and can be reared artificial diets. Relatively little known about the underlying genetic adaptations its feeding habits. Results We report first high-quality genom...
