A field experiment to evaluate the efficacy of pungam (Millettia/Pongamia) oil soap at four different concentrations against brinjal fruit and shoot borer (BFSB), Leucinodes orbonalis Guenee and its effect on spiders of brinjal field revealed that application of 3% pungam oil soap brought down fruit damage to minimum level (12.94% on 7 days after third spray) followed by chlorantraniliprole 18.5% SC (0.3 mL/L), 2, 1 and 0.6% pungam oil soap and neem oil soap 0.6%. Efficacy of chlorantraniliprole persisted up to 14th day of spray followed by pungam oil soap. None of the botanical or chemical pesticides found to influence the spider population until seven days. After 14 days of application soap solution either alone or with pungam oil increased spiders over the control whereas 14 DAS it was minimum in standard check.

A study was conducted from January to June 2019 in Dhading district to identify the effective commercial insecticide against fruit and shoot borer of brinjal (Leucinodes orbonalis). A field experiment was conducted in Randomized Completely Block Design with five treatments (T1: Spinosad @ 1 ml/ 3 liters, T2: Chlorantraniliprole 1 ml/ 3 liters, T3: Cypermethrin 3 ml/ 1 liter, T4: Neem 3 ml/ 1 liter and T5: Control) and four replications. Result indicated that the fruit infestation percent and shoot damage reduction percent, fruit infestation reduction percent were highly significant with the application of insecticides. The shoot damage percent and fruit damage percent was the lowest with spinosad followed by chlorantraniliprole, cypermethrin and Neem. Thus, spinosad is the most effective insecticides for the management of fruit and shoot borer of brinjal in field conditions.

Field studies on evaluation of pongamia and neem oil soap at various concentrations against okra leaf hopper, Amrasca biguttula biguttula (Ishida) was carried out during the year 2018- Treatments i.e. T1: Pongamia oil soap 0.6%; T2: Pongamia oil soap 1%; T3: Pongamia oil soap 2%; T4: Neem oil soap 0.6%; T5: Soap solution 0.5%; T6: Quinalphos 25 EC @ 0.05%; T7: Standard check applied once at vegetative stage and twice during reproductive stage. Quinalphos 25 EC @ 0.05 % was effective followed by pongamia oil soap 2 per cent, pongamia oil soap 1 per cent, neem oil soap 0.6 per cent and pongamia oil soap 0.6 per cent. The effectiveness of the soap reduced after seven days of treatment.

Efficacy of pongamia oil soap against cowpea aphid, Aphis craccivora infesting vegetable cowpea, Vigna unguiculata was evaluated during rabi and summer seasons in comparison with neem oil soap, spinosad, soap solution and absolute control. Pongamia oil soap 2 per cent showed the highest efficacy without phytotoxicity followed by 1 per cent while neem oil soap 0.6 per cent was on par with pongamia oil soap 0.6 per cent. All treatments having pongamia oil soap were significantly superior to absolute control.

Resistant Genotypes

The main purpose of this study was to find out the best variety of brinjal having resistance to BSFB. A pot experiment was carried out at the germplasm centre, Agrotechnology Discipline, Khulna University, Khulna during February 2014 to August 2014. The experiment was laid out in CRD using thirteen varieties with five replications. The varieties were V1=BARI begun-1, V2=BARI begun-4, V3=BARI begun-5, V4=BARI begun-6, V5=BARI begun-7, V6=BARI begun-8, V7=BARI begun-9, V8=BARI begun-10, V9=Makra, V10=Muktokashi, V11=Lalita, V12=Hazra, V13=Chaga. Data were collected on total number of shoot, total number of infested shoot, percentage of shoot damage, percentage of shoot infestation reduction, numbers of larvae per infested shoot, total number of fruit, percentage of fruit damage, percentage of fruit infestation reduction, numbers of larvae per infested fruit. Results have shown that the minimum shoot infestation was found in BARI begun-6 (29.60%, 32.40%, 29.86% and 29.38%, respectively at four different stages of eggplant). Percent of fruit infestation was minimum in V4 (BARI begun-6) (25.16%, 27.42% and 25.40% at three stages respectively).J. Bangladesh Agril. Univ. 16(2): 227-231, August 2018

Field experiment was conducted to check the efficacy of the pongamia oil soap along with Spiromesifen and Neem oil soap at different concentrations in controlling chilli mite, Polyphagotarsonemus latus and its impact on spider population. Spiromesifen was found effective against chilli mite and showed persistent action in the field, whereas pongamia oil soap reported an immediate control over the pest but its effectiveness declined with time and concentration. Among the botanicals, 3% pongamia oil soap was found effective and was followed by the 2% pongamia oil soap. Pongamia oil soap proved effective against mite up to seven days after the treatment and the effect declined by 14 days after the spray. The botanicals as well as the chemical spiromesifen were found safe to spiders in the field.

AbstractThe status of insecticide resistance in field populations of eggplant fruit and shoot borer, Leucinodes orbonalis (Guenée) (Lepidoptera: Crambidae) from the major vegetable growing regions of India was determined during the cropping seasons of 2009–2010 and 2010–2011. Six commonly used insecticides: carbaryl, chlorpyriphos, deltamethrin, endosulfan, fenvalerate, and profenofos were tested against L. orbonalis larvae. The resistance ratios (RR) at the lethal dosage (LD)50 levels were estimated as RR=LD50 field strain/LD50 susceptible strain. The L. orbonalis populations exhibited widespread resistance to tested insecticides. The highest average RR in the two-year study was observed in the assays of populations with deltamethrin (21.50–82.42-fold) followed by assays conducted with endosulfan (24.47–68.26-fold), chlorpyriphos (22.17–63.14-fold), carbaryl (39.18–49.09-fold), and fenvalerate (14.00–44.66-fold); and the lowest average RRs were observed in the assays with profenofos (16.65–39.43-fold). The high levels of LD50 values can be attributed to the long-term indiscriminate use of these insecticides in eggplant (Solanum melongena Linnaeus; Solanaceae) growing regions.
