AbstractResidue analysis of apple foliage obtained from an orchard treated with the insecticides cypermethrin, fenvalerate, deltamethrin, permethrin, and azinphos-methyl revealed detectable residues on the leaves 8–9 weeks after the last treatment. Laboratory studies of foliage showed that of the synthetic pyrethroids, permethrin was initially as toxic as the other synthetic pyrethroids; however, its toxicity decreased considerably by the 5th and 6th week post-treatment. Azinphos-methyl was the least persistent and toxic insecticide evaluated. Unless new pest-management strategies are developed, the use of synthetic pyrethroids post-bloom in an integrated-pest-management program would not be desirable where Amblyseius fallacis (Garman) is the principal predator of phytophagous mites.

Diatraea saccharalis F is considered the most important pest of sugarcane in the United States. This article focuses on the history of pest management as it relates to the control of this stem borer in Louisiana sugarcane, and how control practices have become more in tune with integrated pest management paradigms. Various pest management strategies are employed against D. saccharalis and the interactions between each of these provide farmers with the tools needed to curb damaging infestations. However, the invasion of the Mexican rice borer, Eoreuma loftini (Dyar), and other confounding environmental factors have presented farmers, consultants, and researchers with new pest management challenges. We address these challenges and provide an overview of ongoing developments, particularly in the Louisiana sugarcane pest management program.

Vine Mealybug

Mealybugs (Hemiptera: Pseudococcidae) cause major economic losses in many Tunisian grapegrowing areas. In an attempt to improve management strategies for the Vine Mealybug (VM) Planococcus ficus (Signoret), three insecticides, imidacloprid, Prev-Am® and spirotetramat, were evaluated for their effect on this insect on vine, with reference to methidathion. The systemic insecticide spirotetramat (Movento® 150 OD) provided the greatest control performance of the VM populations, compared to the contact insecticide methidathion, the systemic insecticide imidacloprid applied through furrow irrigated system, and to Prev-Am®, a new contact biopesticide. Three weeks after treatment, VM eggs and adult females were missing from spirotetramat-treated vines. Additionally, spirotetramat supplied a long-residual activity against VM populations and prevented further spread of these insects on vine leaves. Therefore, this new systemic insecticide could be incorporated in an Integrated Pest Management program for VM control in Tunisian vineyards. Despite its short-residual activity, Prev-Am® was shown to be more effective than both methidathion and imidacloprid, mainly on VM eggs and L3 nymphs, and resulted in the highest level of VM L1-L2 nymph decrease on vine trunks. Hence, this biopesticide might prove useful for VM management in vineyards.

Cabbage aphid, Brevicornye brassicae (Linnaeus) is one of the major insect pests of cabbage. Chemical control is mostly used to manage this pest. The present investigation was conducted to evaluate an environmentally benign approach for the pest management through different entomopathogenic mycoformulations against nymphs of B. brassicae to identify effective mycoformulation. The effect of mycoformulations supplemented with different adjuvants against nymphs of B. Brassicae was also evaluated under laboratory conditions. The bioassay studies of fungal bioformulation against nymphs of B. brassicae recorded maximum cumulative per cent mortality (53.33%) in talc formulation of L. lecanii MTCC 956 and commercial L. Lecanii formulation @12g L-1 and these were at par with each other. Maximum percent reduction of nymphal population over control 54.66 and 51.33 per cent was recorded @12 g L-1in talc formulation of L. lecanii (MTCC 956) and commercial L. Lecanii formulation ten days after treatment respectively. Laboratory studies undertaken to evaluate talc formulation of L. lecanii MTCC 956 lecanii with and without adjuvants against the nymphs of B. brassicae recorded maximum percent increase in mortality over control (7.89%) in L. lecanii formulation + tween80@1%. Results of this study signified that L. lecanii formulation, when supplemented with adjuvants enhanced the growth of L. lecanii and increased mortality of nymphs of B. brassicae and could be used as a part of the integrated pest management program.

Field-based residual bioassays and residue analysis were conducted to assess the field performance and toxicity longevity of different insecticides that had previously been associated with resistance of Choristoneura rosaceana populations collected from apple and cherry orchards. In this study, 12–24 h-old larvae of apple and cherry populations were exposed to apple and cherry leaf samples, respectively, at post-application intervals and a susceptible population served as a reference of each. In the apple and cherry trials, the order of residual longevity of insecticides that effectively controlled the tested populations was as follows: bifenthrin and spinetoram (apple: 14, cherry 21-day post-application), phosmet (apple: 7, cherry 14-day post-application), chlorantraniliprole (apple: 7-day post-application), and indoxacarb and emamectin benzoate (apple: 1, cherry 7-day post-application). Compared to the susceptible population, the resistant populations resulted in a measurable loss of field performance, or “practical resistance”, for the insecticides emamectin benzoate (at 7-day post-application), chlorantraniliprole (at 21-day post-application), and indoxacarb (at all post-application intervals) in the apple trials, while in cherry trial just indoxacarb at 7-day post-application showed a reduced efficacy. In terms of long-lasting residues, only chlorantraniliprole and indoxacarb maintained measurable leaf residues over all post-application intervals while the leaf residues of the other compounds had largely degraded within the first 7 days. These findings can help fruit growers make adjustments to their spray/re-application intervals and optimally utilize important chemical tools in their integrated pest management programs.

AbstractA key element of a project designed for integrated pest management in alfalfa fields in New York State is a comprehensive simulation model. The model was developed as a guide for growers to determine when the costs of control measures against alfalfa weevil would be worthwhile. The model incorporates crop and insect submodels. Optimization techniques were used to identify the more cost effective of the possible management strategies. The project has been an unqualified success from a research standpoint but the results are not widely implemented by growers. In this respect, the project has suffered from institutional problems at the research level, lack of confidence and commitment in extension, and skepticism among growers. To rectify this situation, project staff recently adopted new approaches for implementing the program.

Objective: Periplaneta americana (L.) is the most important invasive urban pests in sewers with high significance of public health. The aim of the study was to evaluate the efficacy of several insecticide formulations against American cockroaches in sewers. Methods: The population density of cockroaches was estimated before and after 1 and 5 months of the use of insecticides in sewer manholes. About 10 manholes were allocated for treatment of each insecticide formulation. Twenty manholes were allocated to controls (without the use of insecticides). Insecticides were considered effective achieving more than of 90% mean density reduction of cockroach population per a manhole. Results: The effectiveness of insecticide formulations in sewer manholes were considered effective after 1 month of insecticide treatments while the effectiveness of diazinon EC 5% and 0.05% formulations considered insufficient including 47.% and 19.5%mean density reduction of cockroaches, respectively. The effectiveness of chlorpyrifos EC 5% and Fog, and diazinon EC 5% were observed about 80.5%, 81.5%and 53.5% mean density reduction of cockroaches, respectively after 5 months of treatment while the other formulations did not achieve effectiveness. Conclusions: The insecticide formulations were considered effective and ineffective after 1 and 5 months of the use of insecticides, respectively. It would be more satisfied if insecticide formulations repeated every three months. A reasonable manner is using a combination of integrated pest management strategies recommending for successful P. americana control. Bangladesh Journal of Medical Science Vol.20(3) 2021 p.569-585
