BIOEFFICACY OF NEONICOTINOID INSECTICIDES AGAINST THRIPS PEST (Thrips palmi) ON GRAPE VINE (Vitis vinifera L.) |  UTTAR PRADESH JOURNAL OF ZOOLOGY

The grape thrips (Thrips palmi) is a major pest that causes significant losses in commercial grape production (Vitis vinifera L.). In West Bengal, India, it has become a significant pest of grape vine. The efficacy of neonicotinoid insecticides spinetoram 10% w/w + sulfoxaflor 30% w/w WG @ 100, 120, and 140 a.i. g /ha, spinetoram 12 percent SC w/v (11.7 percent w/w), sulfoxaflor 24 percent w/v (21.8 percent w/w) SC, emamectin benzoate 5% SG and bu Spinetoram 10% w/w + sulfoxaflor 30% w/w WG @ 140 g a.i./ha was the most effective against thrips on grapes, and it was on par with spinetoram 10% + sulfoxaflor 30% WG @ 120 g a.i./ha. The same tendencies can be seen in yield. The pesticides tested were also found to be less toxic to predators such as Menochilus sp., Syrphus sp., and Chrysoperla sp.

In vivo SCREENING OF TURMERIC (Curcuma longa) IN BROILERS CHALLENGED WITH EIMERIAL INFECTION |  UTTAR PRADESH JOURNAL OF ZOOLOGY

The goal of this study was to compare the anticoccidial efficacy of Turmeric (Curcuma longa) to a reference medicine, Amprolium, against experimentally produced Eimeria species infection in broiler chickens raised throughout the Kashmir Valley. Nonetheless, Turmeric rhizomes are an efficient alternative to coccidiostats, but their application is not well understood. One-day-old broiler chicks were acquired from a local store and randomly separated into four groups for this experiment (Group A- Group D). Except for Group D, all of the groups were given 10000 live sporulated oocysts of mixed Eimeria species orally. Group A was infected and treated with Turmeric powder at a dose rate of 5 g/L of drinking water; Group B was infected and treated with Amprolium powder at a dose rate of 1.25 g/L of drinking water; Group C (+ve control) was kept as an infected and untreated group; and Group D (-ve control) was kept as an uninfected and untreated group. Faecal samples were taken on day “0” before treatment and on days 7, 10, 14, and 21 after therapy began. When compared to pre-treatment, both treatments resulted in lower clinical symptoms, lesion score, and faecal Oocyst Per Gram (OPG) counts. The results also revealed that chicks who had diarrhoea in the early days of infection had regular faeces by the 10th day following therapy. On day 21, the maximum efficacy of Turmeric@5g/liter of drinking water was 99.07 percent, which was equivalent to the efficacy of a conventional anticoccidial medicine Amprolium on the same day, which was 99.26 percent. On day 7 compared to all other days, both groups (Turmeric and Amprolium treated) demonstrated a significant difference in efficacy (P0.05). Turmeric was found to be effective in the treatment and control of coccidiosis, with efficacy comparable to that of the standard anticoccidial medication Amprolium.

EFFICACY OF DIFFERENT INSECTICIDAL TREATMENT SCHEDULES AGAINST MANGO LEAF GALL MIDGE Procontarinia matteiana, (KIEFFER & CECCONI) | UTTAR PRADESH JOURNAL OF ZOOLOGY

India is the largest producer of mango in the world but in terms of productivity, it is the lowest among the top five countries. One of the major problems facing the mango industry is pest complexes that damage fruits, flowers, stems, and leaves. Mango is attacked by more than 400 pests in the world. Mango leaves are attacked by many species of Cecidomyiidae especially of the genera Procontarinia. The most common and widespread species is Procontarinia matteiana (Kieffer & Cecconi), a well-known pest of mango in Asia and Africa. The adult midge is a minute fly and dies within 24 hours of emergence after copulation and oviposition. On hatching maggots bore inside the leaf tissues, and feed within, resulting in the formation of small wart-like galls on leaves. Heavily galled leaves curled up and drop prematurely. As a result, it hampers the photo-synthetic efficiency and upset normal physiological activity of the tree resulting in reduced yields of mango fruits. Therefore a study was conducted at a private orchard in Chhotajagulia, North 24 Parganas, West Bengal, India on selected uniform plants (cv. Himsagar) to evaluate the bioefficacy of new insecticides mixtures along with conventional insecticides against mango leaf gall midge in two consecutive seasons (2017-18). The experiment was laid in a randomized block design with three replications of each treatment and an untreated check of water spray. The experiment comprised of eight treatments including the control. Five hundred leaves were randomly selected from a branch to observe and calculate the percentage of newly formed as well as mature galls on fresh leaves. The damage was assessed at weekly interval by counting total leaves versus the infested one. From the study it is revealed that the combination of beta-cyfluthrin 9% +imidacloprid 21% 300 OD@ 75 g a.i/ha was most effective to reduce leaf gall infestation followed by thiamethoxam 12.6% + lambda cyhalothrin 9.5% 247 ZC @ 22 g a.i/ha.
