Determination of hormoligosis of organophosphate insecticides against Phenacoccus solenopsis

Brazilian Journal of Biology, 2022
Cotton mealybug is a highly invasive pest of agricultural crops worldwide. Major agriculturists most rely on the use of insecticides for the control of pesticides. So, the indiscriminate use of insecticides leads to resistance development in recent years.

Exploring the Influence of Insect Honeydew on Plant Physiology and Health: Bridging the Gap in Current Understanding. [PDF]

Physiol Plant
ABSTRACT Honeydew, a sugary excretion from sap‐feeding insects, significantly influences plant‐insect interactions. While extensive research has examined honeydew's composition, regulation, and role in insect‐plant relationships, its direct effects on plant physiology and health remain understudied.

Efficacy of cinnamon oil and its active ingredient (cinnamaldehyde) on the cotton mealy bug Phenacoccus solenopsis Tinsley and the predator Chrysoperla carnea

Bulletin of the National Research Centre, 2020
Background The importance of Chrysoperla carnea (Steph.) (Neuroptera: Chrysopidae) as a predator is due to nourishing this predator on some dangerous pests as the cotton mealybug, Phenacoccus solenopsis Tinsley, belongs to Hemiptera: Pseudococcidae.

Integrating bioassays and transcriptomics to detect neonicotinoid resistance in Australian Bemisia tabaci MEAM1

Pest Management Science, EarlyView.
The Bemisia tabaci MEAM1 strain GR15‐1R shows partial resistance to neonicotinoids (bottom), which correlates with an increased expression of the P450 gene CYP6CM1 compared to the insecticide‐susceptible strain SU07‐1 (top). Abstract BACKGROUND Bemisia tabaci MEAM1 is a highly invasive and polyphagous pest species of agricultural and horticultural ...

A horizontally acquired pantothenate gene drives vitellogenin's benefit to whitefly symbiosis persistence

Insect Science, EarlyView.
This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

A Review on Cotton Mealybug (Phenacoccus solenopsis Tinsley) and their Management by Botanical Based Insecticides

, 2021
Mealybug species becomes major pests in a relative short period of time due to their wide range of host plants, having wax coated body, less effective to insecticides, relationship with ants by these increases their survival rate. Most effective chemicals are Buprofin, Profenofos,Chlorpyrifos,Imidacloprid,but it causes environmental threats, so other ...
