Gram pod borer (Helicoverpa armigera) is a major insect pest of chickpea. The gram pod borer begins to infest at vegetative stage and later feeds on flowers and developing pods. A field investigation was conducted to evaluate the bioefficacy of certain new molecule insecticides against Helicoverpa armigera (Hübner) on chickpea during Rabi 2020-21 in randomized block design with three replications. The outcomes revealed that the application of Chlorantraniliprole 18.5% SC @ 25g a.i./ha and Cyantraniliprole 10.26% OD @ 60g a.i./ha were established to be most effective treatments and application of Fipronil 5% SC @ 50g a.i./ha was least effective in respect of reduction of H. armigera larval population. The maximum yield was recorded in Chlorantraniliprole 18.5% SC @ 25g a.i./ha (14.00 q/ha) followed by Cyantraniliprole 10.26% OD @ 60g a.i./ha (13.73 q/ha) and lowest yield was recorded from Novaluron 75g a.i./ha (10.15 q/ha) treated plot.  The economics of different new molecule insecticides indicated that higher benefit cost ratio (BCR) was observed from Lambda Cyhalothrin 30g a.i./ha (7.86:1) followed by Emamectin benzoate 12g a.i/ha (6.75:1) and the lower BCR was recorded from Cyantraniliprole 60g a.i./ha (1.64:1) and Novaluron 75g a.i./ha (1.58:1). Chlorantraniliprole and Cyantraniliprole are newer group of insecticides, which are relatively safer and more effective against gram pod borer as comparison to conventional insecticides and can be used in successful management of this key pest of chickpea.

Aim: To assess the impact of various temperature regimes on the biology and predatory potential of ladybird beetle, Coccinella septempunctata under laboratory conditions. Methodology: Five treatments and four replications were used for observing the biology and predatory potential on different temperature regimes under laboratory conditions on field-collected mustard aphid, Lipaphis erysimi as a host. Results: Among different temperature regimes, the maximum fecundity and hatchability recorded were 250.67±9.50 and 80.07±0.95, respectively, at 30±2oC. Total grub and adult maximum predatory potential were 238.00±0.50, 508.00±2.65 and 556.33±2.84 at 30±2oC and the minimum were 180.00±5.00, 446.00±12.76 and 493.33±15.28, respectively, at 40±2oC. Interpretation: The present study revealed that 30±2oC temperature was most congenial for the development of Coccinella septempunctata under laboratory conditions and it could be used for mass multiplication of this aphidophagous insect. Key words: Coccinella septempunctata, Ladybird beetle, Predatory potential, Temperature regimes

Prior reports of tubouterine anastomosis following Essure removal involve a cornual resection. We present a novel technique that does not require cornual resection. We also present the outcomes of three cases performed using this method. Design: Video and case series. Settings: A large academic medical center. Patients: The video is of a 30-year-old G2P2 with a history of pelvic pain for four years believed to be secondary to the Essure microinsert placed six years prior. The patient also desired restoration of fertility. The outcomes of two additional patients who underwent this procedure are also reported. Interventions: Bilateral laparoscopic Essure reversal. Measurements/Results: The video demonstrates laparoscopic Essure removal under hysteroscopic guidance followed by laparoscopic tubouterine reanastomosis along a tubal stent. Postoperative hysterosalpingogram demonstrated bilateral tubal patency. A total of three women have undergone this procedure without complications. All three have had postoperative confirmation of unilateral or bilateral tubal patency, however no pregnancies over 2 to 8 months of follow-up. Conclusions: Laparoscopic Essure reversal with restoration of tubal patency can be achieved without a cornual resection. More data is needed on this novel technique, including pregnancy outcomes.
