Experiments were conducted to observe mating and oviposition behabiour as well as biology of hog-plum beetle. Results revealed that the average mating frequency, mating duration and mating interval were 11.2, 30.5 hours and 60.3 hours, respectively. The highest number of eggs per clusters was on leaf rachis followed by young stem. The mean number of eggs per cluster was 15.70 while the length and breadth of an egg was 1.95 mm and 0.60 mm, respectively. The mean duration of 1st, 2nd, 3rd and 4th instar larvae were 3.80, 3.40, 3.70 and 3.00 days, respectively. The mean pupal period was 22.74 days. The female beetle lived longer (48.30 days) than the male (45.10 days). The size of female beetle was larger (15.30 mm) than male (11.96 mm). The mean length of antennae was 7.42 mm. The length of fore, mid and hind legs were 9.20, 9.50 and 11.70 mm, respectively. Hind wings were larger (16.10 mm length and 7.85 mm breadth) than fore wings (12.38 mm length and 5.30 mm breadth).Bangladesh J. Agril. Res. 42(3): 503-508, September 2017

Experiments were conducted in the laboratory to study the effects of garlic clove, neem and eucalyptus leaf extracts on mating behaviour, oviposition and adult emergence of pulse beetle, Callosobruchus maculatus. Intensity of seed damage and weight loss of gram seeds were also recorded. The results showed that the mating frequency, mating duration, oviposition, adult emergence of pulse beetle and weight loss of gram seeds were reduced significantly after application of the extracts. Among the extracts, neem leaf extracts showed lowest mating frequency (1), mating duration (3.66 minutes), lowest number of laid eggs (27.33), adult emergence (11.67), seed damage (6.89%) and weight loss (2.53%). On the other hand, garlic clove extract showed highest mating frequency (1.67), mating duration (4.67 minutes), highest number of laid eggs (40.33), adult emergence (18.66), seed damage (9.63%) and weight loss (3.73%). In the same way eucalyptus leaf extract showed 2nd highest mating frequency (1.5), mating duration (4.5 minutes), eggs laid (38.67), adult emergence (15.67), seed damage (9.25) and seed weight loss (3.33%). Considering efficacy of all extracts, it was found that the order of toxicity was neem leaf extract>eucalyptus leaf extract> garlic clove extract.DOI: http://dx.doi.org/10.3329/pa.v18i2.18164 Progress.

An experiment was carried out at the Experimental Center La Raya-Universidad Nacional del Altiplano Puno, to determine the effect of copulation duration on ovulation and pregnancy in alpacas. 47 adult females were used (postpartum time ≥ 20 days and presence of a follicle ≥ 7 mm) distributed in three groups, according to copulation time: 20, 35 and 50 min, for G1 (n = 15), G2 (n = 16) and G3 (n = 16), respectively. For the mating, 6 reproducers of proven fertility were used, interrupting the copulation at the established time. Ovulation and pregnancy rates were evaluated on days 7 and 30 post service respectively (by ultrasound and receptivity of the female), the data were analyzed using X2 and simple correspondence. Both the ovulation rate (G1: 73.33%, G2: 81.25% and G3: 81.25%); and pregnancy (G1: 53.33%, G2: 81.25% and G3: 75%) were not different (P> 0.05). Pregnancy rates between G1 and G2 tended to be different (P <0.10), consistent with the simple correspondence analysis. Despite there being no differences in ovulation and pregnancy rates, there was a higher percentage trend in G2 and G3, suggesting that the longer duration of mating would have some positive effect on them, according to the simple correspondence analysis, and the trend of low significance (P <0.10) in favor of pregnancy in G2 compared to G1. In conclusion, there were no significant differences in the effect of copulation duration on ovulation; however, there was a 90% trend for the difference between mating duration of 35 minutes versus 20 minutes (in pregnancy).
