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.

Hogna Helluo

While a great deal of research has examined mate choice, variation in behavior during copulation can also have important consequences for the fitness of males and females. We examined the relationships between male and female characteristics (age, size and condition) and copulation duration in the wolf spider Hogna helluo (Araneae, Lycosidae). In addition, we used these relationships to test if males control copulation duration. In this species, males mount the dorsal surface of females and females make no visible attempts to terminate mating. Male age was positively related to the duration of copulation. In addition, male condition was negatively related to the duration of copulation such that poor condition males mated for longer durations. If a group of outlier copulations are removed from the analysis, then male age is no longer a predictor of mating duration but male condition becomes an even stronger predictor of mating duration. Males that engaged in long copulations were more likely to be cannibalized following mating. Our data provide support for the hypothesis that males exert the primary influence on copulation duration in H. helluo . Older and poor condition males may engage in longer copulations to increase their paternity with the current female because they may have a lower chance of escaping postcopulatory sexual cannibalism or surviving to find another female.
